GUN WITH REVERSIBLE SHOULDER-PIECE Application filed February 13, 1913, Serial No. 748,194. Renewed February 10, 1914.

To all whom it may concern:

Be it known that I, OSCAR KNooH, residing at Essen-on-the-Ruhr, Germany, a subject of the Emperor of Germany, have invented a certain new and useful Improvement in Guns with Reversible Shoulder- Pieces, of which the following is a specification.

This invention relates to guns with shoulder piece and consists in a particular arrangement of the shoulder piece.

One embodiment of the invention has been illustrated in the accompanying drawing, wherein- Figure 1 is a side view, partly in section, of gun and mount, with the gun in horizontal position and Fig. 2 a similar view to Fig. 1, with the gun in high elevation.

The gun has a pedestal A, wherein the forked pivot B is mounted with its vertical pivot pin 6 The forked pivot has bearings for the horizontal trunnions c on the cradle C, which latter carries the gun barrel D.

A shoulder piece E is supplied for aiming the gun, which shoulder piece near one end thereof is mounted on a stock 0 The stock 6 is carried, by means of its journal 6 in a socket 0 provided on the cradle C, and may be secured in two different positions 180 apart, by a lock bolt 0 The axis of the s cket intersects the horizontal axis of the trunnions c at an angle of 90. The rest 6 of the shoulder piece E, against which the sighting gunner leans, is curved concentric tothe axis of the trunnion 0 If the gun has to be fired under depression or under slight elevation, the shoulder piece E takes the position relative to the gun indicated in Fig. 1, wherein the rest 6 hangs below the stock 6 The gun may then be aimed conveniently, up to an elevation of some 20 by the sighting gunner leaning with his shoulder against the rest 6 If the gun on the other hand has to be fired at high elevation, the stock 6 is first turned 180 in the socket c after removing the lock bolt 0 whereupon it is again secured by the lock bolt 0 The rest 6 of the shoulder piece E is then situated above the stock 6 see Fig. 2, so that the sighting gunner may conveniently lay the gun, by means of the shoulder piece, up to the highest elevation.

The described arrangement of the shoulder piece ofiers the advantage, that the gun may conveniently be given any elevation by Specification of Letters Patent.

Serial No. 817,880.

means of this comparatively short shoulder piece, measured in the length direction of the rest e 1 I claim:

1. A reversible shoulder piece for guns, comprising a shoulder rest and a stock for carrying said rest; the axis of said stock intersecting the axis of the horizontal gun trunnion, said shoulder rest being curved concentric to the trunnion axis and constructed to be turned around said stock axis and to be secured in either of two opposite positions in the same vertical plane.

2. A reversible shoulder piece for guns, comprising a shoulder rest and a stock for carrying said rest; the axis of said stock intersecting the axis of the horizontal gun trunnions, said shoulder rest being curved concentric to the trunnion axis; a socket for said Stock on a part that partakes of the elevation of the gun, a key for locking said stock in said socket; said shoulder piece constructed to be turned in said socket and se cured by said key in two opposite positions in the same vertical plane.

3. A reversible shoulder piece for guns, comprising a shoulder rest and a stock for carrying said rest; the axis of said stock intersecting the axis of the horizontal gun trunnions, said shoulder rest being curved concentric to the trunnion axis; a socket for said stock on a part that partakes of the elevation of the gun, a key for locking said stock in said socket; said shoulder piece constructed to be turned in said socket and secured by said key in two opposite positions in the same vertical plane; whereby it will be possible to conveniently lay the gun in any elevation from lowest depression to highest elevation.

4:. A shoulder piece for guns, comprising a shoulder rest and a stock for carrying said rest; the axis of said stock intersecting the axis of the horizontal gun trunnion, said shoulder rest being curved concentric to the trunnion axis and constructed to be turned around said stock axis and to be secured in either of two opposite positions in the same vertical plane.

5. A shoulder piece for guns, comprising a shoulder rest and a stock for carrying said rest; the axis of said stock intersecting the axis of the horizontal gun trunnions, said shoulder rest being curved concentric to the trunnion axis; a socket for said stock on a part that partakes of the elevation of the gun, a key for locking said stock in said socket; said shoulder piece constructed to be turned in said socket and secured by said key in two opposite positions in the same vertical plane.

6. A shoulder piece for guns, comprising a shoulder rest and a stock for carrying said rest; the axis of said stock intersecting the axis of the horizontal gun trunnions, said shoulder rest being curved concentric to the trunnion axis; a socket for said stock on a part that partakes of the elevation of the gun, a key for locking said stock in said socket; said shoulder piece constructed to be turned in said socket and secured by said key in two opposite positions in the same vertical plane; whereby it will be possible to conveniently lay the gun in any elevation from lowest depression to highest elevation.

7. A shoulder piece for guns comprising a shoulder rest and a member connecting the shoulder rest with the gun cradle; a receiver on the gun cradle for said member, said member having two positions in the receiverfwhereby said shoulder rest may be positioned below said member for low gun elevation and above said member for high gun elevation, both said positions being in the same vertical plane, said shoulder rest being curved concentric to the axis of the 7 horizontal gun trunnions.

8. A shoulder piece for guns, comprising a shoulder rest and a stock therefor, a socket on the gun cradle constructed to receive the end of said stock; said end having two selectlve positions in said socket whereby said shoulder rest may be positioned below said sition for high gun elevations; and means for locking the shoulder piece in any one of said positions, said shoulder rest being curved concentric to the axis of the horizontal trunnions of the gun.

10. A shoulder piece for barrel recoil guns comprising a shoulder rest and a stock connecting the shoulder rest with the gun cradle, said shoulder rest having two stationary positions by means of said stock allowing the shoulder rest to be positioned below said stock for low gun elevations and above said stock for high gun elevations, said stock being inclined in regard to the longitudinal axis of the gun barrel in such a manner that the connecting point between said shoulder rest and its stock in any one of said positions of the shoulder rest lies above said axis of the gun barrel.

The foregoing specification signed at Barmen, Germany, this 31st day of January, 1913.
